Application filed September 23, 1908. Serial No. 45%,436.

To all whom it may concern:

Be it known that I, HENRY SMITH, a citizen of the United States, and aresident of Bellingham, in the county of Vhatcom and State ofWashington, have invented certain new and useful Improvements in Lawn-Mower Trimming Attachments, of which the following is a specification.

My invention relates to an improvement in lawn mowers and consists in aseparate out ter extending beyond one of the driving wheels of themachine, means for attaching the same to the machine and means fordriving said cutter.

The object of my invention is to provide a readily attachable anddetachable device for a lawn mower which is so located that it can beused to trim the borders not accessible to the cutter of the ordinarylawn mower.

My device is illustrated in the accompanying sheet of drawings in whichsimilar characters refer to similar parts throughout.

Figure 1 is an elevation of the right-hand end of the machine, Fig. 2 isa plan view, F in. 8 is an elevation of the left-hand end sf tnemachine, and Fig. 4 is a sectional View of a part of one of the mowerside cast ings and my attachment where cut by a medial, longitudinal,vertical plane through line a? y of Fig. 2.

More specifically, 1 and 2 are the driving wheels of the lawn mower, 3,3 are the knives, 3 the cutter head, 3 the cutterhead shaft, 4 thehandle, 5 the roller, 6 and 7 the side castings and 13 the shear plate.These are parts of a lawn mower as ordi narily built. The new partsrepresenting my invention are as follows:

8 is a sprocket wheel attached to the driving wheel 1.

10 is a sprocket wheel fastened to one end of shaft 11.

9 is a chain meshing with sprocket wheels 8 and 10.

15 is a fixture attachable to side casting 7 by bolt 16 through slot 16,and furnishes the bearing 15 for shaft 11.

17 is a fixture attachable to side casting 6 by bolt 18 through slot 18,and furnishes the bearing 17 for shaft 11.

12, 12 are the knives of the trimming cutter, secured to trimming cutterhead 12'. Trimming cutter head 12 is fastened to the right-hand end ofshaft 11. A steady clamp is composed of the two parts 19 and 20, each ofwhich is bent over at one end and contains a slot in the other end.These are placed with slotted ends overlapping and bent-over ends lyingabove and below side casting 6 in which position they are clamped tofixture 17 by screw 21. Shear plate 1a which cooperates with thetrimming cutterhead is provided with a right angle bend at one end whichis secured to fixture 17 by screws 14". This shear plate is also pro--vided with finger 1 1 projecting forward from the extreme right-hand endof the same. Shaft 11 is mounted in its bearings parallel with shaft 3",sprocket wheels 8 and 10 are in the same plane. Trimming cutter 2, 12extends beyond drive wheel 2. Finger 1 1 extends beyond the outer end oftrimming knives 12, 12.

It may be observed that this device can be detached from the lawn mowerby the removal of bolts 16 and 18, which are bolts used in the machineas ordinarily built, and of clamp 19, 20 and tension on chain 9 can beadjusted by the use of slots 16 and 18.

Having thus described my invention, 1 claim:

1. In a lawn mower, drive wheels and a main cutter-shaft and a cuttercarried thereby, in combination with a second shaft, a trimming cutteron one end of said second shaft, a shear plate attached to one of thesides of the lawn mower cooperating with said trimming cutter, aremovable attachmentfastened to each side of said lawn mower, saidattachments furnishing bearings for said second shaft and so locatedthat said second shaft may be parallel with the main cutter shaft ofsaid mower, a sprocket wheel on the other end of said second shaft, asprocket wheel on one of said drive wheels and a chain over saidsprocket wheels.

2.
